问题描述
这是我想做的事的一个例子:
from typing import TypeVar # will Awaitable help?
AsyncFn = TypeVar('AsyncFn') # how to narrow this type deFinition down to async functions?
def my_decorator(to_decorate: AsyncFn) -> AsyncFn:
async def decorated(*args,**kwargs): # mypy keeps saying "Function is missing a type"
return await to_decorate(*args,**kwargs)
@my_decorator
async def foo(bar: int) -> str:
return f"async: {bar}"
@my_decorator
async def quux(spam: str,**eggs: str) -> None:
return
foo(1) # should check
foo("baz") # mypy should yell
quux("spam") # should check
quux(1) # mypy should complain
quux(spam="lovely",eggs="plentiful") # ok
quux(spam=1,eggs=0) # mypy should throw a fit
